First, square both sides. This will cancel out the radical.

(a^2 = b + 6)
Then subtract 6 from both sides
b = a^2 - 6
I think they are perpendicular to each other
Does this have anything to do with school? Do you need help sir?
Answer:
8 pints because 16 cups is one gallon so 4 pints is one gallon
Step-by-step explanation:
The steps are duplicated.Then, first I will write the steps in the right form:
19 = 5x - 1
20 = 5x
4 = x
Now, I will write the steps with the justification
19 = 5x - 1.... start
20 = 5x ..... Reason: addtion property of equality (you get this by adding +1 to both sides of the previous equality)
4 = x .... Reason: division property of equality (you get this by dividing by 5 both sides of the previous equality)
